AD9644 is a 14-bit, 80 MSPS/155 MSPS, 1.8 V dual serial output analog-to-digital converter (ADC) that features low power, a flexible analog input range, and a programmable internal ADC voltage reference.
The AD9644 is a dual, 14‑bit analog‑to‑digital converter designed for high‑speed communications applications. It provides serial JESD204A outputs, low power consumption, and flexible input ranges, all in a compact 48‑lead LFCSP package.
The datasheet includes functional block diagrams, pin configurations, electrical specifications, timing parameters, and ordering information, enabling designers to integrate the part into radar, wireless, software‑defined radio, and other high‑performance systems.
| Maximum Sampling Rate | 80 MSPS or 155 MSPS |
|---|---|
| Power Consumption (80 MSPS, sine wave input) | 423 mW |
| Signal‑to‑Noise Ratio (70 MHz, 80 MSPS) | 73.7 dBFS |
The AD9644 can operate at either 80 MSPS or 155 MSPS.
Typical power consumption is 423 mW for a sine‑wave input at 80 MSPS.
It is supplied in a 48‑lead Lead Frame Chip Scale Package (LFCSP).
